Is that the shorter configuration? Looking at the 5842m version, the GT3s last year were only running 2:03.

The GT3 cars running in GT Open are in Super GT regulation not the regular FIA GT3/BES GT3 which laps in 2:04s at cold weather,2:06-:07 in hot weather.So I wouldn't consider them as proper GT3 cars.At silverstone GT Open cars are as much as 4s faster during qualifying than regular GT3 cars,sometimes as fast as 2007 GT1 cars.
